y\v. iM'lt I'emarked, after reading his paper, that a l»ulletin concern- 

 ing the ,iirai)e root-woi-m was now in the hands of the i)rinter, and 

 would be disti-ibuted at an early date. He had found that where 

 poison was a[)plied to foliage which made a rapid growth, as is the 

 case with grape vines in the spring, that it was not elfective in hold- 

 ing this insect in check. 



Mr. Gillette stated tlial during tlie past year apple and clieny trees 

 in Colorado had been badly infested with aphi(b's. He had found 

 I'rom obsiM'vation, however, that many of the eggs which Wi'i-e deposited 

 in the fall failed t() hatch during tlie following spring. He estimated 

 that not one in 1,000 of the eggs laid in the fall of VM>2 hatclied last 

 spring. In spite of this fact there was an al)undanco of plant-lice 

 pi-esent in June. 



INfi-. C'ooley luid ob.served the same fact in ^Montana, and remarked 

 thai many growers were inclined to give up apple culture because of 

 the serious damage to young orchards caused by the a])i>le aphis.

 abundant and dcsti-oyed many of the lice.
